exhaust resonator delete pipe

An exhaust resonator delete pipe replaces the factory resonator with a straight section of pipe, removing the resonator entirely from the exhaust system. The resonator is a secondary sound-dampening chamber positioned after the catalytic converter and before or after the muffler. Removing it increases exhaust volume and changes the tone of the exhaust note, typically making it louder and more aggressive. Resonator delete pipes are a low-cost way to change the sound character of a vehicle without replacing the muffler or the full exhaust system.
